IPC: G01N21/72
Filed: 1962-08-27
Abstract: 970,249. Testing gases photo-electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 8, 1963 [Aug. 27, 1962], No. 32759/62. Headings G1A and G1B. A method for the detection of volatile organic halides e.g. carbon tetrachloride, tetrachloroethane, dichlorodifluoromethane in gaseous atmospheres comprises sampling the gas atmosphere, passing the sample to a flame heating a copper element and analysing the green flame colour produced by the halides using a photo-sensitive cell. A gas burner is fitted with an ejector to feed contaminated air to the gas flame at a constant rate, the burner being adjusted to give a "non-luminous" flame. A copper rod is located in the flame so that volatile organic halides in the flame will colour it green. A part-spherical mirror and collimating lens system is used to focus the most intense colouration on a copper-copper oxide photo-voltaic cell which has its terminals connected by means of a convenient range setting switch to a mirror galvanometer which throws a light spot on a scale. The green light from the flame may be suitably filtered, if desired, to cut out interfering light.

Title: Improvements in and relating to wired broadcasting of colour television
Inventor: ADORIAN PAUL
IPC: H04N11/12
Filed: 1953-11-26
Abstract: 768,682. Television distribution systems. COMMUNICATIONS PATENTS, Ltd. Feb. 25, 1955 [Nov. 26, 1953], No. 32884/53. Drawings to Specification. Class 40 (4). In a distribution system for colour television at least two distribution circuits are used to carry information concerning the picture. Thus in one embodiment two circuits are used, one carrying a luminance signal and the other a chrominance signal. The luminance signal is caused to modulate a carrier signal which is fed to one of the circuits and the chrominance information is transmitted in the form of hue and colour saturation signals which modulate different carrier frequencies which are then combined for transmission over the second circuit. In a second embodiment the luminance signal is sent over one two-wire circuit, the colour saturation signal over a second twowire circuit and the hue signal is sent over the phantom of these two circuits. The three signals may be derived direct from a camera, or from a radio receiver for receiving broadcast colour signals. The audio signals may be sent over one of the circuits, e.g. the luminance circuit. In the case where a plurality of olour programmes is to be transmitted, additional carrier waves for carrying the additional programmes may be superposed on the circuits carrying the first programme.

Title: Improvements in the production of ferrochromium
IPC: C22C35/00
Filed: 1955-11-21
Abstract: Ferro-chromium is produced by heating chrome ore (e.g chromite) with calcium carbide silica to a temperature of over 1400 DEG C. Chromium-containing material such as converter slag, electric furnace slag, or chromic oxide may be added to enrich the mixture.  A two-stage process may be used for ores of low ratio of chromium to iron content, the first stage being a partial reduction to remove iron using a stoichiometric deficiency of the carbide (in admixture with silica), or of carbonaceous agents such as coal, coke, in the presence of slag-forming material such as lime-stone, dolomite or silica.  In an example 10 parts of a chrome ore (containing 49 per cent chromic oxide), 3 1/2 parts technical grade calcium carbide (containing 82 per cent Ca C2), and 3 parts silica rock or sand (93 per cent SiO2) were ground to minus 30 mesh, intimately mixed and heated in a silica lined electric arc furnace to 1500 DEG -1600 DEG C., the ferro-chromium forming a molten bath under the fluid slag.  A typical alloy contains 49.3 per cent Cr, 1.5 per cent C, 8.5 per cent Si and the balance Fe apart from small amounts of impurities such as Al, V, Ti.  Such alloy may be further treated with more chromite and/or chromium enriched material in an electric or other furnace at 1400 DEG C. or higher to produce a low carbon ferro-chromium.
